Which consequence results when a radio antenna is shorter than optimal for broadcasting?

💡 Explanation

Shorter antennas have lower radiation resistance, curtailing power transmitted efficiently; therefore, electromagnetic wave propagation distance decreases because radiated power is lower, rather than impedance matching requirements changing directly or spurious emissions being amplified.
